Sorry, but you can't double-dip and not expect to get burned. You are clearly attempting to get double compensation from paypal buyer protection AND sell off the marker in parts.

That being said, I am pretty sure you can easily fix your "leaking" issue.
1) inspect O-rings are perfect or replace O-rings (especially the cup seal, that is the O-ring most prone to wear/damage)
You can even just flip the cup seal around so its using a fresh surface, see if that helps. Make sure you are not missing any O-rings, refer to user manual.
2) reinstall all air fittings with teflon tape
3) cut and use new macrolines

Because you attempted to sell off the parts in pieces and not assembled, I can only assume you are having trouble reassembling everything. Please refer to user manual located on phantomonline.com
